Description

Technical Field

[0001] The present invention relates to the technical field of baggage sorting, and in particular to a method for determining baggage position, a sorting system and a computer storage medium. Background Art

[0002] The departure carousel is located at the end of the airport baggage system, which can collect and cache the baggage delivered by the conveyor line. In order to improve operational efficiency, there are often baggage from multiple flights on the carousel. When the operator picks up the baggage of a specified flight on the carousel, he needs to check all the baggage tags one by one, which is inefficient. The sorting system can detect the position of the baggage on the carousel and prompt the flight information of the corresponding baggage on the screen, thereby reducing the ineffective labor of the operator and improving work efficiency.

[0003] The existing luggage location detection method is to detect through conventional photoelectric detection (Solution 1). For Solution 1, that is, the conventional photoelectric detection scheme can only detect the starting position of the luggage on the carousel, and cannot detect the situation where multiple luggage are connected or stacked. In addition, the existing luggage location detection method also includes a detection method based on Radio Frequency Identification (RFID) (Solution 2). For Solution 2, that is, the RFID-based detection scheme is to detect the luggage tag. Since RFID technology itself does not support positioning detection, it cannot accurately locate the luggage on the carousel. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the existing baggage position detection scheme cannot accurately locate the baggage on the carousel. The present invention provides a method for determining the baggage position, a sorting system, a computer storage medium and a program product, which can improve the accuracy and work efficiency of detecting the baggage position.

[0009] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a method for determining the location of luggage, the method for determining the location of luggage further comprising: obtaining a third distance when the carrier with the set number passes through the first sensor at a third moment, the third moment being later than the first moment; and determining that the third distance is greater than the second distance, and determining that luggage has been taken away from the carrier with the set number.

[0010] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a method for determining the position of luggage, wherein the third distance includes: the distance from the side of the turntable away from the first sensor to the first sensor; or the distance from the side of the luggage carried by the set numbered carrier close to the first sensor to the first sensor.

[0011] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a method for determining the location of luggage, wherein determining that the third distance is greater than the second distance and determining that luggage on the carrier with the set number has been taken away further includes: when determining that the third distance is greater than the second distance and the third distance is equal to the set distance value, determining that all luggage on the carrier with the set number has been taken away; or when determining that the third distance is greater than the second distance and the third distance is less than the set distance value, determining that not all luggage on the carrier with the set number has been taken away.

[0012] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a method for determining the location of luggage, the method for determining the location of luggage also includes: obtaining flight information of luggage carried by a carrier with a set number when it passes through an RFID device, and displaying the flight information of the luggage and the number information of the carrier with a set number on a display device.

[0013] An embodiment of the present invention further discloses a sorting system, comprising: a turntable having a plurality of sequentially numbered carriers, the carriers being configured to carry and transport luggage; a first sensor disposed on the turntable; a second sensor disposed on the turntable, the second sensor being disposed downstream of the first sensor along a conveying direction of the turntable; and a controller connected to the first sensor and the second sensor, respectively, the controller being used to execute the method for determining luggage location described in any possible embodiment described above.

[0018] By adopting the above technical solution, the present invention aims at solving the problem that it is difficult to accurately locate the position of luggage on the turntable in the actual application of the existing luggage positioning solution.

[0019] Furthermore, since each carrier on the turntable of the embodiment of the present application is numbered in sequence, the number of the carrier carrying the luggage is confirmed, and the number of the carrier is bound to the carried luggage, so that the corresponding position of the carrier on the turntable is determined according to the number of the carrier carrying the luggage, and the position of the luggage carried by the carrier on the turntable can be determined, and the luggage position can be accurately located, so as to improve the accuracy and work efficiency of detecting the luggage position and improve the working environment.

[0040] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0041] Figure 1 According to some embodiments of the present application, a schematic diagram of a scenario in which a sorting system 1 determines the position of luggage on a turntable is shown.

[0042] like Figure 1 As shown, a sorting system 1 provided in an embodiment of the present application includes: a turntable 10, a baggage induction device 20, a display device 30, a first sensor 41, a second sensor 42, an RFID device 50 and a controller (not shown in the figure).

[0043] Specifically, Figure 1 As shown in FIG. , along the conveying direction of the baggage induction device (such as Figure 1 As shown in the Y direction, one end 201 of the baggage induction device is connected to the upper side of the turntable 10 so that the baggage (for example Figure 1 The luggage #5 shown in the figure can enter the carrier 11 of the turntable 10 from one end 201 of the luggage induction device through the luggage induction device 20. The turntable 10 drives the multiple carriers 11 to move along the conveying direction of the turntable (such as Figure 1 The carrier 11 is used to carry luggage. The luggage #1, #2, #3 and #4 are all carried by the carrier 11 and move synchronously with the carrier 11 along the conveying direction X of the turntable.

[0044] For example, Figure 1 As shown in FIG. 1 , the turntable 10 is provided with a plurality of sequentially numbered (eg Figure 1 The carrier 11 is a scale 11 (shown as scales 11 numbered 11 to 30 in the figure). For example, by installing an encoder on a motor (not shown in the figure) of the turntable 10, the scales 11 are numbered according to the conveying direction X of the turntable (such as Figure 1 30 to 11 in the figure). However, the present invention is not limited thereto. The encoding method of the scales 11 is not specifically limited in the present invention. For example, the encoding may be performed by visual detection. In addition, the number of scales 11 is not specifically limited in the present invention. For example, the number may be 10, 50, 80, 90, 100 or more.

[0045] It should be noted that Figure 1 Only a portion of the turntable 10 is shown in the figure, and the embodiment of the present application does not specifically limit the shape of the turntable 10. For example, the turntable 10 can be in other shapes such as a ring.

[0046] The display device 30 is provided on the upper side of the turntable 10, and the display device 30 extends along the conveying direction X of the turntable. Along the conveying direction X of the turntable, the RFID device 50 is provided between the baggage induction device 20 and the display device 30, and the RFID device 50 is used to detect the baggage (such as Figure 1 The display device 30 receives the flight information from the controller and displays the flight information and number information (e.g., Figure 1 VI1234-ARM and VI6666-SHA are shown in FIG. 1 and 10 respectively, and the luggage on the carousel 10 is displayed in a one-to-one correspondence. For example, the display device 30 in the embodiment of the present application is a display screen.

[0047] For example, Figure 1 As shown in , in the horizontal direction (i.e., along the conveying direction X of the turntable), the 1# bag is arranged on the right side of the 2# bag along the conveying direction X of the turntable, and the 3# bag is located between the 1# bag and the 2# bag. In the height direction (i.e., along the height direction Z of the carrier 11), the 3# bag is stacked on the upper side of the 1# bag and the 2# bag along the height direction Z of the carrier 11, that is, the projections of the 3# bag, the 1# bag and the 2# bag in the height direction Z partially overlap.

[0048] Accordingly, in the display area of ​​the display device 30, in the horizontal direction (i.e., along the conveying direction X of the turntable), the flight information of the 1# baggage (such as Figure 1 VI6666-SHA) is also located in the flight information of baggage No. 2 (such as Figure 1VI1234-ARM in the figure) along the right side of the conveying direction X, and the flight information of baggage #3 (such as Figure 1 1 and 2) are located between the flight information of the 1# baggage and the flight information of the 2# baggage, and the flight information of the 3# baggage overlaps with the projection of the flight information of the 1# baggage and the flight information of the 2# baggage in the height direction Z. In the height direction (i.e., the height direction Z of the carrier 11), the flight information of the 3# baggage is located above the flight information of the 1# baggage and the flight information of the 2# baggage along the height direction Z of the carrier 11, and corresponds to the position of the 3# baggage on the carousel 10.

[0049] That is, the flight information of the luggage in the display device 30 corresponds to the luggage mapping on the carousel 10. Exemplarily, in the horizontal direction and the height direction, the flight information of the luggage in the embodiment of the present application corresponds to the middle part of the luggage on the carousel 10; but not limited to this, the embodiment of the present application does not limit the correspondence between the flight information of the luggage and the luggage on the carousel 10. For example, in the horizontal direction, the flight information of the luggage may correspond to the head of the luggage on the carousel 10, and in the height direction, the flight information of the luggage may correspond to the bottom of the luggage on the carousel 10.

[0050] Therefore, in the embodiment of the present application, the flight information of the luggage in the display area of ​​the display device 30 corresponds to the luggage mapping on the carousel 10, so that the position and flight information of each luggage on the carousel 10 can be presented to the user (for example, the operator) in a more intuitive form, avoiding the operator from checking the luggage tags of all the luggage on the carousel 10 one by one, thereby reducing the ineffective work of the operator, improving the working environment of the operator, and improving the accuracy and work efficiency of detecting the luggage position.

[0051] Since the conventional photoelectric detection method (Solution 1) can only detect the starting position of the luggage on the carousel, and the RFID-based detection solution (Solution 2) does not support positioning detection, the luggage on the carousel cannot be accurately located.

[0052] In order to solve the above problem, an embodiment of the present application provides a method for determining the position of luggage, by which a plurality of sensors arranged on a turntable are used to obtain whether there is luggage on the carriers numbered in sequence, and the position of the carriers with the number on the turntable is determined according to the number of the carriers carrying the luggage, thereby determining the position of the luggage on the turntable and achieving accurate positioning of the luggage.

[0053] Continue to refer Figure 1The above-mentioned sensors include a first sensor 41 and a second sensor 42. Along the conveying direction X of the turntable, the first sensor 41 and the second sensor 42 are respectively arranged on opposite sides of the baggage induction device 20, and the second sensor 42 is arranged between the first sensor 41 and the RFID device 50. The first sensor 41 and the second sensor 42 are respectively connected to a controller (not shown in the figure).

[0054] It should be noted that the embodiment of the present application does not specifically limit the positions of the first sensor 41 and the second sensor 42. For example, the first sensor 41 and the second sensor 42 may also be arranged at the same side of the baggage induction device 20 along the conveying direction X of the turntable, as long as the first sensor 41 can detect the first distance of the support member 11 passing the first sensor 41 at a first moment and the second sensor 42 can detect the second distance of the support member 11 passing the second sensor 42 at a second moment.

[0055] The following is based on Figure 1 The schematic diagram of the sorting system 1 shown in FIG. Figure 2 The method for determining the luggage location of the present application is described in detail.

[0056] Specifically, in the embodiments of the present application Figure 2 The method for determining the luggage position can be implemented by the controller of the sorting system 1 executing a related program.

[0057] refer to Figure 2 According to a specific embodiment of the present application, a method for determining luggage location includes the following steps.

[0058] S1: Obtaining a first distance of a carrier with a set number when it passes through a first sensor at a first moment.

[0059] Here, the controller of the embodiment of the present application is electrically connected to the turntable 10 (for example, an encoder installed on the motor of the turntable 10), so that the controller can obtain the number of the scales 11 on the turntable 10 in real time. In addition, the controller of the embodiment of the present application is electrically connected to the first sensor 41, so that the controller can store and update the distance information of the scales 11 with the set number obtained by the first sensor 41. For example, the distance information of the scales 11 passing through the first sensor 41 obtained by the first sensor 41 at the first moment is stored as the first distance H0.

[0060] In the examples of this application, refer to Figure 3a , wherein the turntable 10 is at a first moment (i.e., moment t0, for example, the 10th second), along the height direction of the scale (e.g. Figure 3aAs shown in the Z direction, the distance from the side 1001 of the turntable at the first sensor 41 away from the first sensor to the first sensor 41 is a set distance value H (for example, 60 cm), which is a fixed value, and the height of the luggage is h0 (for example, 25 cm).

[0061] For example, Figure 3a As shown in , the luggage lies horizontally on the turntable 10, and the height h0 of the luggage represents the distance from the side of the luggage away from the first sensor 41 to the side of the luggage close to the first sensor 41 along the height direction Z; but not limited to this, the embodiment of the present application does not specifically limit the posture of the luggage. For example, the luggage can also be upright on the turntable 10, and the height h0 of the luggage represents the distance from the bottom of the luggage away from the first sensor 41 to the top of the luggage close to the first sensor 41 along the height direction Z. In addition, the embodiment of the present application does not limit the size of the set distance value H, and it can be specifically set according to actual conditions. For example, the set distance value H can be smaller than the width of the turntable 10 in the height direction Z.

[0062] Continue to participate Figure 3a , at the first moment t0 (10s), the scale 11 with number 8 is located below the first sensor 41, and the distance from the side 1002 of the luggage carried by the scale 11 with number 8 close to the first sensor to the first sensor 41 is H-h0. That is, at the first moment t0, the first sensor 41 detects that the first distance of the scale 11 with number 8 is H0, and H0=H-h0 (i.e., 35cm).

[0063] S2: Obtaining a second distance of the carrier with a set number when it passes through the second sensor at a second moment.

[0064] Here, the controller of the embodiment of the present application is electrically connected to the second sensor 42, and the controller of the embodiment of the present application can store and update the distance information of the scale 11 with a set number obtained by the second sensor 42. For example, the distance information of the scale 11 passing through the second sensor 42 obtained by the second sensor 42 at the second moment is stored as the second distance H1.

[0065] In the examples of this application, refer to Figure 4 , wherein the turntable 10 is at a second moment (ie, moment t1, for example, 20 seconds), and the second moment t1 is later than the first moment t0.

[0066] like Figure 4As shown, at the second moment t1 (20 seconds), the scale 11 with number 8 moves to the bottom of the second sensor 42, and the distance from the side 1002 of the luggage carried by the scale 11 with number 8 close to the second sensor to the second sensor 42 is H-h0. That is, at the second moment t1, the second sensor 42 detects that the second distance of the scale 11 with number 8 is H1, and H1=H-h0 (i.e., 35 cm).

[0067] S3: Compare the first distance and the second distance.

[0068] Here, the controller of the embodiment of the present application can obtain the stored distance information about the scale 11 and filter the distance information of the scale 11. Secondly, the filtered distance information is statistically analyzed, and the above distance information may include the updated first distance H0 and second distance H1. That is, when performing the above step S3, the controller can obtain the latest first distance H0 and second distance H1 of the scale 11. Then, the controller compares the values ​​of the above first distance H0 and second distance H1.

[0069] In the embodiment of the present application, the first distance H0 and the second distance H1 are compared to determine whether the scale 11 numbered 8 carries luggage.

[0070] It can be understood that when the scale 11 carries one or more pieces of luggage, Figure 3a As shown in , the scale 11 with number 8 passes the first sensor 41 at the first moment t0, and the first distance of the scale 11 with number 8 detected by the first sensor 41 is the distance from the side of the top luggage close to the first sensor 41 to the first sensor 41 (i.e. H0). At this time, the value of the first distance H0 is less than the maximum value (i.e. the set distance value H). When the scale 11 does not carry luggage, as shown in Figure 4 As shown in , the scale 11 with number 13 passes the first sensor 41 at the first moment t0, and the first distance H0 of the scale 11 with number 13 detected by the first sensor 41 is the distance from the side 1001 of the turntable away from the first sensor to the first sensor 41 (i.e., the set distance value H), and the value of the first distance H0 is the maximum value at this time. That is, the value of the first distance H0 when the scale 11 does not carry luggage is greater than the value of the first distance H0 when the scale 11 carries one or more luggage, and the value of the corresponding first distance H0 decreases with each additional luggage carried by the scale 11.

[0071] In other words, the value of the distance measured by the sensor when the scale 11 is not carrying luggage is greater than the value of the distance measured by the sensor when the scale 11 is carrying one or more luggage, and the value of the distance measured by the corresponding sensor decreases with each additional luggage carried by the scale 11. Therefore, the embodiment of the present application can determine whether the scale 11 is carrying luggage based on the magnitude relationship between the first distance H0 when the scale 11 passes the first sensor 41 at the first moment t0 and the second distance H1 when the scale 11 passes the second sensor 42 at the second moment t1.

[0072] S31: Determine that the second distance is smaller than the first distance, and determine that the carrier with the set number carries luggage.

[0073] If the controller of the embodiment of the present application determines after comparison that the second distance is smaller than the first distance, it means that the second distance is smaller than the set distance value H, that is, the scale 11 carries one or more luggage when passing the second sensor 42 at the second moment, and it is determined that the scale 11 carries luggage.

[0074] In the embodiments of the present application, for example, reference is made to Figure 3b Combined with Figure 4 The value of the second distance H1=H-h0 (ie, 35 cm) of the scale 11 numbered 8 is smaller than the value of the first distance H0=H (ie, 60 cm).

[0075] Therefore, it is determined that the scale 11 with number 8 carries baggage. Furthermore, the scale 11 with number 8 carries baggage newly introduced into the carousel 10 from the baggage induction device 20 .

[0076] S32: When it is determined that the second distance is equal to the first distance and the first distance is less than the set distance value, it is determined that the carrier with the set number carries luggage.

[0077] If the controller of the embodiment of the present application determines after comparison that the second distance H1 is equal to the first distance H0, and the first distance H0 is less than the set distance value H, it means that the scale 11 carries one or more luggage when it passes through the first sensor 41 at the first moment t0, and the scale 11 carries the same number of luggage at the second moment t1 as at the first moment t0, then it is determined that the scale 11 carries luggage.

[0078] In the embodiments of the present application, specifically, continue to refer to Figure 4 Combine Figure 3a , the value of the first distance H0 of the scale 11 numbered 8 (ie, 35 cm) is equal to the value of the second distance H1 (ie, 35 cm), and the value of the first distance H0 (ie, 35 cm) is less than the set distance value H (ie, 60 cm).

[0079] Therefore, it is determined that the scale 11 with number 8 carries baggage. Furthermore, the baggage on the scale 11 with number 8 has not changed, and the scale 11 with number 8 does not carry baggage newly introduced into the carousel 10 from the baggage induction device 20.

[0080] In summary, combined Figure 3a and Figure 4 According to the above steps S1 to S3 of the method for determining the luggage position of the present application, it is determined in sequence that the first distance H0 of the scales 11 adjacent to number 9 and 10 of number 8 is equal to the second distance H1, and the first distance H0 of the scales 11 adjacent to number 9 and 10 is less than the set distance value H. That is, the change trend of the first distance H0 and the second distance H1 of the scales 11 adjacent to number 9 and 10 of number 8 is the same as the change trend of the scale 11 of number 8, while the first distance H0 and the second distance H1 of the scales 11 of number 7 and 11 are equal to the set distance value H and have not changed. That is, the change trend of the first distance H0 and the second distance H1 of the scales 11 of number 7 and 11 is different from the change trend of the scale 11 of number 8, so it can be determined that the scales 11 of number 8 to 10 carry luggage together. That is, it is determined that the luggage is located at the scales 11 of number 8 to 10 on the carousel 10.

[0081] It can be seen that the above Figure 2 The method for determining the position of luggage is shown. When the sorting system 1 needs to determine the position of the luggage on the carousel 10, the controller can automatically start the above method to determine whether the scale 11 in the carousel 10 carries luggage, to determine the number of the scale 11 carrying the luggage, and to bind the luggage to the number of the scale 11. Thus, according to the number of the scale 11 carrying the luggage (for example, the scale 11 numbered 8 to 10 above), the corresponding position of the scale 11 on the carousel 10 is determined, and the position of the luggage carried by the scale 11 on the carousel 10 can be determined, so as to accurately locate the position of the luggage on the carousel 10, so as to improve the accuracy and work efficiency of detecting the luggage position and improve the working environment.

[0082] In addition, reference Figure 5 Step S31 may further include step S311: when it is determined that the second distance is smaller than the first distance and the first distance is smaller than a set distance value, it is determined that the carrier with a set number carries a plurality of luggage stacked along a height direction of the carrier.

[0083] As mentioned above, if the second distance H1 is smaller than the first distance H0, it is determined that the scale 11 is carrying luggage.

[0084] In the embodiment of the present application, if the controller of the embodiment of the present application determines after comparison that the first distance H0 is less than the set distance value H, it means that the scale 11 has carried one or more luggage when it passes through the first sensor 41 at the first moment t0. Since the second distance H1 is less than the first distance H0, it means that the number of luggage carried by the scale 11 at the second moment t1 is greater than the number of luggage carried by the scale 11 at the first moment t0, and it is determined that the scale 11 carries multiple luggage along the height direction of the scale (such as Figure 1 The stacked luggage (see Figure 1 1#, 2# and 3# luggage stacked in the middle).

[0085] In the above steps S1 to S3, the method for determining the luggage location of the present application can be used to determine the number of the scale 11 carrying the luggage, but is not limited to this. The method for determining the luggage location of the present application can also be used to determine whether any luggage has been taken away from the scale 11 with a set number.

[0086] Below through Figure 6 and Figure 7 Provide detailed explanation.

[0087] S4: Obtaining a third distance of the carrier with a set number when it passes through the first sensor at a third moment.

[0088] Here, the controller of the embodiment of the present application is electrically connected to the first sensor 41, so that the controller can store and update the distance information of the scale 11 with a set number obtained by the first sensor 41. For example, the distance information of the scale 11 passing through the first sensor 41 obtained by the first sensor 41 at the third moment is stored as the third distance H2. Figure 7 , wherein the rotating disk 10 is at the third moment (ie, moment t2, for example, the 100th second), and the third moment t2 (ie, the 100th second) is later than the first moment t0 (ie, the 10th second). The scale 11 numbered 8 moves from the second sensor 42 to the first sensor 41 .

[0089] like Figure 7 As shown, at the third moment t2 (i.e., 100 seconds), the scale 11 numbered 8 moves past the first sensor 41, and the distance from the side of the scale 11 numbered 8 close to the first sensor 41 to the first sensor is H (i.e., 60 cm). That is, at the third moment t2, the first sensor 41 detects that the third distance of the scale 11 numbered 8 is H2, and H2=H (i.e., 60 cm).

[0090] S5: Compare the second distance and the third distance.

[0091] Here, the controller of the embodiment of the present application can obtain the stored distance information about the scale 11 and filter the distance information of the scale 11. Secondly, the filtered distance information is statistically analyzed, and the above distance information may include the updated second distance H1 and third distance H2. That is, when performing the above step S5, the controller can obtain the latest second distance H1 and third distance H2 of the scale 11. Then, the controller compares the values ​​of the above second distance H1 and third distance H2.

[0092] In the embodiment of the present application, the third distance H2 and the second distance H1 are compared to determine whether the scale 11 numbered 8 carries luggage to be taken away.

[0093] As mentioned above, the value of the distance measured by the corresponding sensor decreases with each additional piece of luggage carried by the scale 11. Similarly, the value of the distance measured by the corresponding sensor increases with each reduction of luggage carried by the scale 11.

[0094] S51: Determine that the third distance is greater than the second distance, and determine that luggage has been taken away from the carrier with a set number.

[0095] If the controller of the embodiment of the present application determines after comparison that the third distance H2 is greater than the second distance H1, it means that the second distance H1 is less than the set distance value H, that is, the scale 11 carries one or more luggage when passing the second sensor 42 at the second moment t1. Since the third distance H2 is greater than the second distance H1, it means that the number of luggage carried by the scale 11 at the third moment t2 is less than the number of luggage carried by the scale 11 at the second moment t1, and it is determined that luggage on the scale 11 has been taken away.

[0096] In the embodiments of the present application, specifically, continue to refer to Figure 7 Combine Figure 4 , the value of the third distance H2 of the scale 11 numbered 8 (ie, 60 cm) is greater than the value of the second distance H1 (ie, 35 cm). Therefore, it is determined that luggage has been taken away from the scale 11 numbered 8.

[0097] Further, refer to Figure 8 Step S51 may further include step S511: when it is determined that the third distance is greater than the second distance and the third distance is equal to the set distance value, it is determined that all the luggage on the carrier with the set number has been taken away.

[0098] As mentioned above, if the third distance H2 is greater than the second distance H1, it is determined that luggage has been taken away from the scale 11.

[0099] Based on this, if the controller of the embodiment of the present application determines after comparison that the third distance H2 is equal to the set distance value H (i.e., 60 cm), it means that the scale 11 is not carrying any luggage when it passes through the first sensor 41 at the third moment t2, and it is determined that all the luggage on the scale 11 has been taken away.

[0100] In the embodiments of the present application, specifically, continue to refer to Figure 7 Combined with Figure 3a , the value of the third distance H2 of the scale 11 numbered 8 (ie 60 cm) is equal to the set distance value H, then it is determined that the scale 11 numbered 8 does not carry any luggage at the third moment t2, and all the luggage on the scale 11 numbered 8 has been taken away.

[0101] In summary, combined Figure 4 and Figure 7 According to the above steps S4 and S5 of the method for determining the luggage position of the present application, it is determined in sequence that the third distance H2 of the scales 11 numbered 9 and 10 adjacent to number 8 is greater than the second distance H1, and the third distance H2 of the scales 11 numbered 9 and 10 is equal to the set distance value H. That is, the change trend of the third distance H2 and the second distance H1 of the scales 11 numbered 9 and 10 adjacent to number 8 is the same as the change trend of the scale 11 numbered 8, while the third distance H2 and the second distance H1 of the scales 11 numbered 7 and 11 are equal to the set distance value H and have not changed. That is, the change trend of the third distance H2 and the second distance H1 of the scales 11 numbered 7 and 11 is different from the change trend of the scale 11 numbered 8, so it can be determined that the luggage carried by the scales 11 numbered 8 to 10 has been taken away. That is, it is determined that the location of the taken luggage is at the scales 11 numbered 8 to 10 on the turntable 10.

[0102] It can be seen that the above Figure 6 and Figure 8 The method for determining the position of luggage shown in the figure, when the sorting system 1 needs to determine the position of the taken luggage on the turntable 10, the controller can automatically start the above method to determine whether there is luggage taken away from the scale 11 in the turntable 10, to determine the number of the scale 11 of the taken luggage, and bind the luggage with the number of the scale 11. Thus, according to the number of the scale 11 carrying the luggage (for example, the scale 11 numbered 8 to 10 above), the corresponding position of the scale 11 on the turntable 10 is determined, and the position of the luggage carried by the scale 11 on the turntable 10 can be determined, so as to accurately locate the position of the taken luggage on the turntable 10.

[0103] In addition, continue to refer to Figure 8 Step S51 may further include step S512: when it is determined that the third distance is greater than the second distance and the third distance is less than a set distance value, it is determined that not all luggage on the carrier with a set number has been taken away.

[0104] As mentioned above, if the third distance H2 is greater than the second distance H1, it is determined that luggage has been taken away from the scale 11.

[0105] In the example of the present application, if the controller of the embodiment of the present application determines after comparison that the third distance H2 is less than the set distance value H, it means that the scale 11 has carried one or more luggage when it passes through the first sensor 41 at the third moment t2, and it is determined that the luggage on the scale 11 has not been completely taken away.

[0106] In the embodiment of the present application, the sorting system 1 executes the above-mentioned method for determining the luggage position through the controller, so as to realize accurate positioning of the luggage on the carousel 10. In combination with the display device 30 and the RFID device 50 of the sorting system 1, the flight information and number information of the luggage can be displayed one-to-one with the luggage on the carousel 10.

[0107] Below through Figure 1 , Figure 4 and Figure 9a introduce Fig.10 The process of displaying the flight information of the baggage and the number information of the scale 11 with a set number on the display device 30 described in step S6.

[0108] S6: Obtaining flight information of the luggage carried by the carrier with a set number when it passes through the RFID device, and displaying the flight information of the luggage and the number information of the carrier with a set number on the display device.

[0109] Here, the controller of the embodiment of the present application is electrically connected to the display device 30 and the RFID device 50, respectively, so that after the RFID device 50 detects the flight information of the luggage carried by the scales 11 of the RFID device 50, the flight information can be sent to the controller, and the display device 30 receives the flight information from the controller to display the flight information and number information of the luggage corresponding to the luggage mapping on the carousel 10.

[0110] In the embodiments of the present application, Figure 4 As shown in , at this time, baggage #1 is located at the baggage induction device 20. The scales 11 numbered 12 to 16 are not carrying any baggage. That is, the first sensor 41 obtains that the first distance of the scales 11 numbered 12 to 16 passing through the first sensor 41 at the first time t0 (10th second) is H0, and H0=H (i.e., 60 cm).

[0111] like Figure 9a As shown in ( Figure 9a The dotted line structure of the 1# baggage in the figure represents the movement trajectory of the 1# baggage from the baggage induction device 20 into the turntable 10). At this time, the 1# baggage enters the turntable 10 from the baggage induction device 20.

[0112] Here, the second sensor 42 obtains that the second distances of the scales 11 numbered 12 and 16 passing through the second sensor 42 at the second time t1 (20 seconds) are H1, H1=H (i.e., 60 cm). In addition, the second sensor 42 obtains that the second distances of the scales 11 numbered 13 to 15 passing through the second sensor 42 at the second time t1 are H1, H1=H-h0 (i.e., 35 cm).

[0113] The controller compares the acquired first distance H0 with the second distance H1, and can confirm that the second distance H1 (i.e., 35 cm) of the scales 11 numbered 13 to 15 is smaller than the first distance H0 (i.e., 60 cm), thereby confirming that the scales 11 numbered 13 to 15 carry the 1# baggage entering the carousel 10 from the baggage induction device 20. In addition, since the second distance H1 (i.e., 60 cm) of the scales 11 numbered 12 and 16 is equal to the first distance H0 (i.e., 60 cm), and the first distance H0 is equal to the set distance value H (i.e., 60 cm), it can be confirmed that the scales 11 numbered 12 and 16 do not carry any baggage.

[0114] That is, the luggage #1 is carried by the scales 11 numbered 13 to 15. That is, the luggage #1 is located at the scales 11 numbered 13 to 15 in the carousel 10.

[0115] Thus, combined Figure 1 After the luggage #1 is carried by the scale 11 and continues to move along the conveying direction X of the turntable 10 and passes through the RFID device 50, the RFID device 50 checks the flight information and number information of the luggage #1 (for example, Figure 1 VI6666-SHA, and matches the flight information of baggage #1 and the scale 11 carrying baggage #1 through the controller (for example, Figure 9a The flight information of the luggage is associated with the scale 11 (e.g., the scale 11 carrying the luggage #1) and the flight information is associated with the scale 11 carrying the luggage #1. Figure 9a The numbering information of the scales 11) numbered 13 to 15 in the figure is matched one by one.

[0116] Finally, when luggage #1 moves past the display device 30, the controller of the embodiment of the present application controls the display device 30 to display the flight information and number information corresponding to luggage #1, and controls the displayed flight information and number information to move synchronously in the display device 30 relative to luggage #1.

[0117] It can be understood that the scales 11 of the embodiment of the present application will drive the luggage to move synchronously when they move along the conveying direction X of the turntable 10. That is, the position of the scales 11 on the turntable 10 is variable, so the position of the luggage carried by the scales 11 on the turntable 10 is also variable.

[0118] Therefore, when the number information of the scale 11 and the baggage flight information are displayed on the display device 30 in the embodiment of the present application, the method for determining the location of the baggage in the embodiment of the present application can be based on the number of the scale 11 (for example, Figure 9a The corresponding position of the scale 11 on the turntable 10 is determined by using the scales 11 numbered 13 to 15 in the display device 30, thereby determining the position of the luggage carried by the scale 11 on the turntable 10, so that when the scale 11 on the turntable 10 carries the luggage and moves along the conveying direction X of the turntable 10, the number information of the scale 11 can move synchronously with the scale 11 in the display device 30.

[0119] Furthermore, the flight information and number information of the luggage of the sorting system 1 of the embodiment of the present application can synchronously follow the scales 11 and the luggage carried by the scales 11 to move synchronously, avoiding the operator from checking the luggage tags of all the luggage on the turntable 10 one by one, thereby reducing the ineffective work of the operator, improving the working environment of the operator, and improving the accuracy and work efficiency of detecting the luggage position.

[0120] In the embodiment of the present application, if the luggage carried by the scales 11 on the turntable 10 is taken away, Figure 8 As shown in step S51 in the above, the controller of the sorting system 1 can detect the number of the scale 11 carrying the taken luggage through the above-mentioned method for determining the luggage position. Therefore, the position of the luggage on the turntable 10 when it is not taken away can be determined. When the RFID device 50 detects the scale 11 carrying the taken luggage, the RFID device 50 can obtain the flight information of the taken luggage and unbind the flight information of the taken luggage from the scale 11 carrying the taken luggage, so that the controller can control the display device 30 to eliminate the flight information of the taken luggage in the display area.

[0121] Figure 9b A schematic diagram of a sorting system 1 is shown, wherein the turntable 10 is at a time later than Figure 1 The moment at which the turntable 10 is located.

[0122] refer to Figure 9b Combine Figure 1 As mentioned above, the flight information of the luggage in the display device 30 corresponds to the luggage mapping on the carousel 10. For example, Figure 9b As shown, the flight information of luggage #1, luggage #2 and luggage #4 in the display device 30 are mapped to luggage #1, luggage #2 and luggage #4 on the carousel 10 , respectively.

[0123] Specifically, along the conveying direction X of the carousel, luggage #1 is located on the right side of luggage #2, luggage #4 is located on the left side of luggage #2, and the distance between luggage #4 and luggage #2 is greater than the distance between luggage #2 and luggage #1. Figure 9b VI6666-SHA in the table) corresponds to the flight information of baggage No. 2 (such as Figure 9b On the right side of the VI1234-ARM, the flight information of baggage #4 (such as Figure 9b VI1234-ARM in the figure) corresponds to the flight information of the 2# baggage (such as Figure 9b The distance between the flight information of 4# luggage and the flight information of 2# luggage is greater than the distance between the flight information of 2# luggage and the flight information of 1# luggage.

[0124] At this time, luggage #1, luggage #2, and luggage #4 have passed through the RFID device 50 along the conveying direction X of the carousel. That is, the controller has determined that luggage #3 carried by the scales 11 numbered 14 to 17 has been taken away, and the RFID device 50 has detected the scales 11 carrying the taken away luggage and obtained the flight information of the taken away luggage (such as Figure 1 VI1234-ARM corresponding to baggage #3 is shown in the figure).

[0125] Thus, the controller will be taken away 3# luggage flight information (such as Figure 1 3# baggage (as shown in VI1234-ARM corresponding to baggage #3) is untied from the number information of scales 11 numbered 14 to 17, so that the flight information of baggage #3 is eliminated in the display area of ​​the display device 30.

[0126] For example, Figure 1 As shown in , the sorting system 1 of the embodiment of the present application further includes a camera device 60, which is used to capture images of the luggage for subsequent AI segmentation and tracing.

[0127] It should be understood that in the embodiment of the present application, since the multiple carriers 11 on the turntable 10 perform cyclic motion along the extension direction X of the turntable, each time the carrier 11 on the turntable 10 runs to the first sensor 41, a first distance H0 corresponding to the carrier 11 at a different time is generated. Therefore, after the first moment t0, each time the carrier 11 with the same number (for example, the scale 11 with number 8) runs to the first sensor 41 again, the first sensor 41 will re-detect the carrier 11 with the same number to obtain different distances (for example, the first distance and the third distance) of the carrier 11 at different moments (for example, the first moment and the third moment).

[0128] It should be noted that the embodiment of the present application does not impose any specific restrictions on the types of the first distance, the second distance, and the third distance, as long as they can be used to determine whether the carrier 11 with a set number carries luggage. For example, the first sensor 41 may detect the thickness of the carrier 11 passing through the first sensor 41 at a first moment, the second sensor 42 may detect the thickness of the carrier 11 passing through the second sensor 42 at a second moment, and the first sensor 41 may detect the thickness of the carrier 11 passing through the first sensor 41 at a third moment.

[0129] It should be noted that the method for determining the luggage location of the present application is not limited to the above application scenarios, and any application scenario that requires accurate positioning of the target object can be implemented by the method for determining the luggage location of the present application. For example, it can also be used to determine the position of a product on a conveyor belt in a factory assembly line.
